      I don't think conflicts have anything to do with languages. Unfortunately many languages there are becoming extinct. Thanks for visiting and commenting! :)

      Those were some fascinating facts. I found the one regarding Africa's population vs. languages particularly intriguing. I wonder if a common language makes eases conflict? Hmmm.

      Namaste.
